SEVERIN HALVORSEN, OF SEATTLE, WASHINGTON.

NEWSPAPER-STUFFING MACHINE.

Application filed April 15, 1919. Serial No. 290,184.

To all whom it may concern:

Be it known that I, SEVERIN HALVORS-EN, a citizen of the United States, and resident of Seattle, King County, Washington, have invented certain new and useful Improvements in Newspaper-Stuffing Machines, of which the following is a specification.

My invention consists of a machine designed for assembling the various sections of a newspaper which is printed in a plurality of sections, so as to include them all within one cover section. This operation is what is known in' newspaper oflices as stuffing the papers. 4

I, therefore, call my invention a newspaper stufiing machine,

The object of my invention isto provide a machine which will do this work automatically of assembling all of the other sections of a newspaper within one outer or cover section, and to do this with certainty and. rapidity.

The features of my invention which I deem to be new will first be described in the form of construction illustrated in the drawings; and the principles involved therein and the combination of parts which I deem to be new will be particularly defined by the claims.

The accompanying drawings show my present invention in the form of construction which I noy's prefer.

Figure-1 is an end elevation of the machine taken from the head end, that'is the end at which the operation of stufling begins. v

Figure 2 is a transverse sectional elevation taken through the head which carries the paper opening mechanism.

Figure 3 is a section taken through a pair of heads following after that shown in Figure 2, these heads handling insert sections.

Figure 4.- is a side elevation of one end of the machine showing the head which handles the cover section and a part of the next set of heads which handle insert sections.

Figure 5 is an end elevation of the oppok site or delivery end of the machine.

Figures 6 and 7 are transverse sectional Figure 9 is a View showing the means whereby part of the paper opening mecha nism is operated.

Figure 10 shows in perspective the separator plate and spreader together with the pressing foot and the receiving end of the trough by which the paper is opened.

- Figure 11 is asection taken through the paper opening mechanism showing the paper in somewhat diiferent position from that shown in Figure 8.

Figure 12 shows from the inner side an elevation with parts in section of the means employed for operating the reciprocating presser foot by which the paper is opened.

Figure 13 is a top or plan view of the same mechanism.

Figures 14 and 15 are transverse sectional elevations on a larger scale showing more in detail the construction and manner of operation of the presser feet by which the paper is handled in opening.

Figure 16 is a plan view and partial section of the presser foot which engages the back side of the paper section.

Figure 17 is a. perspective showing in section the construction of the paper engaging and feeding member.

Figure 18 shows in perspective the parts of the head section which are employed for opening the cover section with one of the paper engaging presser feet swung outward in position to "-give access to the paper re ceiving pocket. f

Figure 19 is a top or plan view showing the relative position of-the paper opening mechanism and the trough or guide through which the paper is fed while receiving the insert sections.

Figure 20 is a transverse section taken on the line 2020 of Figure 19-.

Figure 21 shows in perspective a section of the feeding chain showing one of the connecting bars by which the paper is engaged for feeding lengthwise of the trough.

Figur'e'22 shows the manner in which the paper feeding chain is operated and its connection with the paper delivering mechanism.

Figures 23 and 24: are respectively horizontal and transverse vertical sections taken respectively on the planes indicated by the lines 23--23 and 24-24 of Figure 4.

Figure 25 is a section takenupon the lines 2525 of Figure 4: showing the relative 1105b tionof the paper feeding rolls.

This machine employs a plurality of paper feeding heads, the number depending upon the number of sections which are to be assembled at one time within one oli these sections.

These various heads are arranged along a central axis, along which axis extends a trough or equivalent paper guiding and feeding niechanisi'n to one end of which the cover section is delivered, "folded edge downward, at which point and as it starts travel along the trough, it is opened to a shape in such manner as to receive the in.- sert sections. The insert sections are delivered from the other heads into this cover section as it passes in front thereof. and the final result, namely, the complete stutl'ed paper, is delivered at the. opposite end of the machine. The number of insert heads employed will depend of course upon the number of sections which are to he assembled .in one paper. 1 have illustrated one cover head and two insert heads; The two insert heads are placed one at each side of the central axis, and the two insert sections are delivered into the cover section at the same time and place.

As many additional insert heads as de sired may he placed in succession alongthe course of the conveyingtrough and these may be placed at both sides of the trough or all at one side, as desired.

In Figure 2 is shown a transve se sectional elevation taken through. one enl of the cover head and that end of the iron h ion while in Figure is shown a. side el of the cover or opening head and a of the adjacent insert head.

T he means for delivering the papers i. a. stack are the same for all of the heads. The particular mechanism employed for this purpose is not material to my presentinvention. it will suilice if it may be depended upon to deliver reliably and accurately a single paper at a time to the opening and the assembling mechanism.

l have shown at 1 stacks of papers. These are put in position within. openings l ullilt'fll by upwardly extending arnis ll": and ll. The two arms ll) are at the side ot the stack of papers which is next to the central axis of the machine. while the arni 11 is at one end of the paper stack.

Associated with these parts are devices whereby one paper at a time is }i"ll{""-ll from the bottom of each stack and is to the opening and assembling parts.

Figures l) and 7 show sectional elevations of these parts.

The papers are taken as the come from the ordinarv press. namely. l'olded transversely across the cene" 'il' the page. 'lhe "i'olded edges oi the iers are placed is towards against the standards l that the central axis of the machine.

Beneath this edge of the stack of pagers are planet supporting or plates ll. which extend only a. short distance under this edge of the paper. 'llhey, however serve tohold this edge of the stack of papers slightly raised. it the same edge of the pile of papers I provide short ileed belts or tapes 123. which are rotated in such main nor as to force the papers downward. t the opposite edge of the stack of papei: is a of urine H which are oscillate npoo a pivotshal t 3* so -ipers up into close cone-cl; it? and tapes 13.

which they are acted upon by the cning mechanism. his receptacle or poc cl), has two side plates 20 sepa 'atcd a short distance. Beneath these, and separated somewhat from their lower edge, is a third plate 21. which is bent into the form of an inverted f, or narrow U. The paper when delivered from the stack is fed into the opening niecaanisui with the folded edge ot the paper lorwa rd. \Vhen received in the opening mechanism it thus stands in vertical position with the folded edge downward.

Supported upon the frame so as to have a reciprocating movement t 'ansverselv thereof. or tovards and from the paper in the opening mechanism is a presser har which is shown in detail in Figure 14% and which is also illust 'ated in Figures 2 11, 14 and 15. This presser har is ,i heing sonar; in cross section. adopted a convenient means for preventing rotation. Otherwise. it 'ght l r: suitable. The end oi this presscr har is provided with a s "X journaicd tl:

e of an eross sectn 0.1181 which engages with the peripheral snriace oi a ram 31. whereh the prcsser ha? is given an intermittent forward feeding movement and is held toiwvai d for a short other half 33. of the presser bar is a 1 with the halt 3). The adjacent ends o? fl two parts are maintained soi'newhat sepa ed. These two parts are cminectiial in sin way that the are normally held apart I spring and also by a holt or other m which limits the amount o't this separzm. In consequence the two parts ma he closer together hut can not he As shown the part 33 is provided v extending lengthwise thereot in 'whic serted a rod 3% carried by the section}. Within the horn in the section 31% plac l a spring which acts to maintain the twi parts in separated position. hat-h parts 3 and 33 are provided with arms 35, through which passes a bolt 231". i justing the position of the nut 38 of this bolt the degree of separationbetween the two parts may he accurately and very minutely controlled. This is veiw desirahle as ot the the position of the working face of this ha r to relative to the paper must he adjusted compensate For different illltliiitHSlS o i sections employed. in other words. a a page cover section requires a difll rent adjustment from that required h v a 16 page cover section.

Upon the end (it the presser har section 33 is placed a foot 39, which is in position to engage the upper edge of the cover section C.

re side paper, this being the side which is towards the main hotly ot the machine, or the direction in which the cover section is ted in order to ret ,'ve the insert sections. The relative position o1 these parts is well shown h; the perspective of Figure 10. it is thus seen that the separator plate 4 engages only vith one corner of the paper, and at a slight distance below ts upper edge. This scparator plate is preferably held in a yielding manner hr hei ,g pivoted at its upper end upon a pin ill and by having a spring ail acting thereon so as to mid its" ne'er dge towards the foot :35) ot' the presser har.

The arm 42 has no movement except one of reciprocation towards and from the paper such as has been described. The block 43 is, however, mounted in the guideways 44 so that it may have a certain amount of vertical reciprocation, that is of movement towards and from the folded edge of the paper in a direction which is substantially parallel with the plane in which the paper is placed.

The block 43 is connected by means of a pin 46, with a rod or link 47. The pin 46 passes through a slot 48 in the arm 45. The

link 47 is secured to an arm 48 which is anounted upon a shaft 49 so as to oscillate. This arm 49 extends transversely of the machine and is provided at its other end with an arm 25 which is connected with a link 26. This link is provided with a cam roller 27 which engages with the surface of a cam 28 carried by shaft 29. The link 27 is shown as having a yoke 24 which embraces the shaft 29 and prevents side movement thereof. In consequence the block 43 is given a reciprocating movement in a substantially vertical direction.

Figure 14 illustrates the position 01": the parts of the opening mechanism when the cover section has been put in lace therein, but before the opening mechanism has acted thereon.

Figure 15 shows the position of the same parts after the block 43 has been moved downward. Prior to the downward movement of the block 43, the cam 31 which acts upon the presser bar 8 and 33, has acted to force the presser foot 39 and the arts 42 towards the paper. This has clamped paper between the arm 42 and the block 43 in such manner as to force the annular rings 50 inward and to insert the needles 5 into the paper. These needles are made of such a length thatthey will not pass beyond the center of the paper from each side. In consequence the needles at one side have no engagement with the half of the paper which is at the opposite side. In consequence, when the block 43 is moved downward, it carries with it its half of the paper. This movement is sufiicient to withdraw that half of the paper from beneath the separator plate 4 and produces a position of the parts such as is shown in Figure 15. The spring acting upon the separator plate causes it to press closely against the front face off the rear halfof the paper which hall? has not been moved downwardly, but which has been held in place. by the engagement of the needles carried by the arm 42. Block 43 then moves upward carrying its half of the paper up with it. As the lower edge of the separator plate 4 is made quite thin, the

upper edge of the outer half of the paper then passes outside of the separator plate.

the cover section in opened. position.

the chains lie.

eaner/e This position of the separator plate with relation to the paper is shown in Figure 10.

By the above mechanism the two halves of the paper have been separated and a separator plate 4 has been inserted between them. This separator plate extends horizontally beyond the edge of the paper in the direction in which the paper is fed for the reception of the insert sections. This outer end of the separator plate is enlarged, as shown at 400. In alinement with this and having a narrow edge which will insure its entering between the 0 sides of the paper. is the spreader 56. the paper be moved edgewise in this direction, it is evident that it will have its two sides separated to such an extent that it will be in position to receive insert sections which may be fed thereto.

Associated with these parts is the trough 6. This has its side walls inclined to each other ata sufiicient angle to insure maintaining The angle of these parts is well. shown in Figures 2 and 11. At the end next to the paper opening mechanisms it is provided with plates which converge towards the opening mechanism and between which and the spreader 56 the two sides of the newspaper pass. Associated with the trough 6 is a paper feeding or carrying chain 61. Two such chains are employed one at each side of the trough. These chains are preferably enclosed within pockets 62, formed in the body of the trough so that the chains themselves may never come in contact with the paper. The inner wall oi? the trough at each side is provided with a slot 63 connecting with the conduit or passage 62, in which Through this extend arms which are connected with bars 64 which extend across the trough. These are placed at such a point as to pass between the lower portion 21 of the pocket which receives the cover section and the parts above the same. They engage the paper point about midway between its upper and lower edges and carry it through the trough. One of these bars is shown in detail by perspective in Figure 21. This is shown as having short arms 65 at its end which slightly overlap the side faces of the paper. The chains (31 are given a contiznious forward movement. They may be driven in any convenient and suitable manner. The manner of driving which has been adopted by me is shown in Figure 22. Two pairs oi? sprocket. wheels 66 are placed at opposi nds of the machine and are driven through chain. (57 and gears as 68. The particular mechanism by which these are driven is, however, immaterial.

At the termination oi the spreader 56 is a retainer'bar 56 which parallels the side of the trough at or below the edge of the cover section as it passes air the nugh to receive the insert sections. This bar is supported by arms 56 of U-shape, from the side of the trough. These arms 56 together with the bar" 56*- hold one side of the cover section down and prevent the inserts from engaging the edges of-the cover section when entering the trough.

To insure that the opposite side of the cover section and the inserts as received are carried to and held close to the opposite wall of the trough, a second series of retaining bars is enployed. The end 56 of these which is towards the cover opening head is positioned close to the bar 56 but the opposite end 56 is curved to the opposite side of the trough. A separate bar of this kind is provided for each insert head to carry the vinsert sections to the opposite side of the trough so that they will be out of the way of the later entering insert sections. such bar thus extends throughout substantially the extent of two heads one endbeing near one side of the trough and the other near the opposite side. By these means the. sections previously inserted do not interfere-v with those inserted later.

The paper after leaving the head which carries the cover section, and after being opened by the mechanism described, is passed along the axis of the machine beneath the various heads in which the insert sections are placed. In Figure 4 I have shown a part of one of these heads. "These have means for holding and delivering thepapers the same as has been described with the first head, or that which contains the cover sections. It is, therefore, not necessary to describe its mechanism in detail and especially as the means for delivering the papers from the' stacks is not a part of this present invention. It will suflice to say that the operation of these devices are timed in such a way as to deliver the insert section of which two are shown at 22 in Figure 3 into the cover section as it passes. The number of insert heads to be employed may be made whatever is desired. They may also be'placed in pairs, one

' at each side of the central axis of the machine as has been shown in Figure 3. When the paper, reaches the delivery end of the machine it is turned down sideways and received upon rolls or feeding-tapes as shown at B in Figure 22. The plate 7 which lies in front of the cover section while, it is being opened is hinged at its "lower edge as shown at so that it may swing outward. Normally this is held up in position by means of a spring as shown at 71. In consequence this may be easily drawn outward if at any time anything happens to a cover section to prevent the proper operation of the parts.

The reciprocating paperopening or feed block 43 is mounted in an arm 45 which in turn is pivoted upon a vertical pivot at 72 Each.

of a spring as 7 5. It is thus easy to release this link and to swing the arm 45 outward.

Thearm 45 is held in working position by means of a pin 76'which passes through holes in cars 77 carried by the arm and by the bracket 7 8 upon which it is pivoted. By removing this pin 76 and pullingdownward the bolt 74 the arm 45 may be swung outward so as to give free access to the paper opening mechanisms.

Vhen the cover section is delivered to the pocket in which it is to be opened it is possible that. when it strikes the bottom thereof it might rebound and thus be caught by the separator plate 4 too far below its upper edge and the opening mechanism thus failv to properly function. To prevent this I provide a lever arm 8 which is pivoted upon a shaft 80 and which is given an intermittent rocking movement through a crank arm 81, link 82. Link 82 is shown as having its opposite end provided with a yoke 83 which spans the shaft 29, and as also carrying a cam roller 84 which engages with a cam 85 by which the link is reciprocated and the paper holding arm 8 is moved toward and from the paper. The backward movement of the link 82 is secured by means of a spring 86. The backward movement of the presser bar 3 is also secured by means of a spring 300. The paper holding arm 8 is provided upon its face wit-h teeth or other means by which it may securely engage and hold the paper.

to. the movement of the paper out of the opening pocket the cam has acted upon the arm 8 in such a manner as to swing it backward and thus release the paper.

A mechanism for opening folded papers for receiving inserts, comprising two members adapted to engage opposite sides of the paper towards the edge of said paper which is opposite to its fold, both of said members carrying means for preventing relative movement between said members and the paper, a separator plate engageable with one face of the paper near the edge which is opposite to the fold, and means for moving one of said first named members to withdraw that side of the paper beyond the line of engagement of the separator plate with the paper.

25.- A, mechanism. for opening folded papers for receiving inserts, comprising two members adapted to engage opposite sides of the paper towards the edge of said paper which is opposite to its fold, both of said members carrying means for preventing relative movement between said members and the paper, a separator plate engageable with one face of the paper near the edge which is opposite to the fold, and means for moving one of said first named members to withdraw that side of the paper beyond the line of engagement of the separator plate with the paper, a spreader alined with the separator plate and means for moving the paper so as topass over said spreader.

26. Ina newspaper stufling machine, means for opening a cover section, means for conveying said paper'in a direction substantially parallel with the direction of its folded edge, a trough receiving and guiding the paper, a spreader positioned to enter between the opened sides of the paper, a retaining bar lying within and close to one side of the opened paper during its said movement, and means for placing the inserts within the opened paper as it passes through said trough.

27. A device for opening a folded paper comprising means for holding one ply of the paper, means for moving the other ply relatively to the first, and separating means adapted to move into position against the inner side of the first mentioned ply when the second mentioned ply is withdrawn, whereby when said second mentioned ply is returned to original position, said separating means will be positioned between said plies. i

28. In a device for separating the plies of a folded paper, a separator plate adapted to engage and be held against a face of the paper adjacent to an edge other than that along which it is folded, a feeding foot adapted to engage the same face of the p aper, and means for reciprocating said feeding foot away from and towards the separator plate to thereby withdraw one ply of the paper from beneath and to then place it over said separater plate.

- 29. In a device for separating the plies of a folded paper, a separator plate adapted to be pressedagainst a face of the paper adjacent to an edge other than that where folded, a feeding foot and a retaining foot engaging opposite faces of the'paper, and means for reciprocating th feeding foot from and towards the separator plate to thereby withdraw one ply of the paper from beneath the separator plate and to then place it at the opposite side of the separator plate.

30. An opening device comprising means for holding one ply, of the paper against movement, means for reciprocating the edgemost portion of the other ply of the paper toward and away from its folded edge, separating means adapted to come into position between the plies when the second mentioned ply is moved back to original position, and means for increasing the separation caused by the interposition of said separating means between said plies.

- 31. The combination with a series of paper receiving heads, means for delivering paper sections from each head, means for opening the paper section from the first head, means for advancing said opened section to receive the sections from the other heads and means for moving the sections from the other heads to one side within the open section to facilitate insertion of successive sections.
